Performance Issues with DSpace 7.5 Groups and Member Searches

[Rift Blaster]

Greetings everyone,

I'm currently utilizing DSpace 7.5, where I've encountered a challenge. Within my system, there are approximately 1000 groups and 2000 members. One particular group contains 1300 members, while others have 50-100 members. When I attempt to search for the group with 1300 members, it takes a considerable amount of time to retrieve the results. I've also conducted tests using hal browser and found that the response time is significantly delayed.

The URL I use for this search is as follows:
/server/api/eperson/groups/6d2c20f0-f1b1-4ce2-b613-8c6816e9b90a/epersons

Even when I limit the search to just one result with the size=1 parameter:
/server/api/eperson/groups/6d2c20f0-f1b1-4ce2-b613-8c6816e9b90a/epersons?page=0&size=1, it still takes 3-4 minutes to receive a response. However, when I search for other groups with fewer members (50-100), the system performs smoothly.

I should mention that this issue is occurring in my local environment, using localhost:8080 and localhost:4000.

I would greatly appreciate any assistance in resolving this issue, and I'm also interested to know if anyone else has experienced a similar problem.

Hi all,

Just an FYI, after some more investigation/discussion via Slack, this thread has been turned into an issue ticket. https://github.com/DSpace/DSpace/issues/9052

We'll be discussing this in this week's DSpace Developers Meeting and trying to locate a volunteer to investigate the issues further.
